So I got a few whisker shrimp yesterday and was a bit worried after I got them that they would kill my neon tetras while they slept, upon coming home from work today expecting to see some dead tetras they where all fine. But then I saw a little piece of clear skin floating around and only 3 out of 4 shrimp. Those little bastards are cannibals! I wish I had seen the fight :( too bad they are nocturnal.

Seeing a piece of clear skin (from the shrimp I take it), doesn't necessarily mean a shrimp has been killed. Shrimp do shed their exo-skeleton and that is clear. Once they shed their new shell needs to harden so they usually hide for awhile.
I'm not sure what whisker shrimp are or what colour they maybe but dont count the shrimp as dead just yet. When a shrimp has died you will usually see some meat with the skin.

A freshly killed shrimp will quickly turn a pinkish white. A shedded skin is translucent white. After moulting shrimps tend to hide for several hours until they've hardened.

I think it's not a good idea to place 4 unknown shrimp in a single tank expecting them to attack and kill eachother and the fish.

I agree with Hardy - why would you purchase these shrimp in the first place if you thought they might attack your neons?

I haven't ever heard the name whisker shrimp before, but I looked it up and it can refer to various species of macrobrachium. If your shrimp have long, pronounced pincers that would also support this.
The various macrobrachium are known to be aggressive, predatory and cannibalistic, and certain species like M. carcinus or M. Rosenbergii can exceed a foot in body length.

May I ask where you got that body length from? Sources I know (including a few scientific papers) say no more than 6 inches and that seems to be confirmed by keepers.

If these are indeed macrobrachium you got a big issue. In many species it's only the males that have the big arms which makes the females less efficient hunters. Despite that they will all have a certain agressive and predatory temperament. They're interesting shrimp to keep and can do well in something as small as a 5-8 gallon (depending on the shape of the tank of course) but they don't mix well with company.

Update: turns out you guys were right! It did just shed its exo-skeleton. And for you whiners no I didnt know they were potential killers until after I bought them. They all seem to be female becasue their claws are extremely small. They would have to coordinate with each other to be able to kill my smallest tetra. But im pretty sure they are too stupid to do that. Biggest issue in my tank now is my white skirt tetras fighting, the big one keeps on nipping at the smallers ones fins and tearin them up. Not sure if I should just flush the s.o.b. or let nature take its course. I guess we'll see how it goes.

You don't ever flush anything, s.o.b. or not.

Please do not flush the fish! There is always an alternative. Can you use a divider? Can you take them to a petshop? Can you give him to someone else, a member on here or elsewhere? There is always a way out of trouble.

I suppose I could take him back if it got that bad. I want to let it play out for a little longer and see if he chills out. But suppose I took all of my white skirts back what would be a good tank mate for my neons and female whiskers?

Yeah, just don't flush him... It's a cruel death, and it isn't the fish's fault he thinks he needs to be bossy. I'd suggest maybe getting rid of the white skirts or the neons, they don't really get along since the skirts are sort of mean-ish and neons are gentle and shy.
Uh... Whiskers can get kind of mean even if they seem small. I had a couple that had little pincers (bought it as a darn ghost shrimp) but then started looking interested in my pencils and I got rid of 'em.
Uh... You could try cories of pretty much any kind? Black neons or penguin tetras for some variety? Glowlight tetras? Maybe a dwarf gourami?

I saw these super rare tetras online called galaxy tetras. They look amazing, they are black with orange dots and orange fins. I'd love to get some of those if I can get my hands on them

Those are celestial pearl danios, although galaxy tetra or galaxy rasbora is what they're sometimes called. I'm pretty sure they're technically danios. If you look under the right name of celestial pearl danios, they aren't crazy rare, just a bit unusual. Try ordering a group online or going to a non-chain store. They're tiny, though, usually about 1/2" when bought and maybe 3/4" when adult. Really big females can reach one inch. I think they'd be okay with neons, but definitely not whisker shrimp or white-skirts. They're definitely schooling fish, so get at least 7, and your tank should be reasonably heavily planted or they'll be really shy and faded out. What size is the tank again? If you can find them, ten or more would look great with a nice school of neons...
Just to let you know, they're more like dark blue in person.


Or did you mean those slim little ones with the huge fanned fins and not the little ones with rounded noses and slightly arched backs? Because I don't know what those are.

Do you think the whisker shrimo will eventually agress my neons? That was my concern but they seem to pretty much keep to themselves. As well as the neons and white skirts, they never bother each other

I suggest you get rid of the whiskers and add ghost shrimps instead. Ghosts stay small and won't be a threat, just make sure you get one of the few species that aren't whiskers.
I don't know if they're a risk... I'd say so, yes.
Keep an eye on the whiteskirts... They might be scaring with the neons with their hectic behavior if they act anything like my blackskirts do. If you keep them, definitely stay away from the celestial pearl danios, the whiteskirts will terrify and possibly eat them.
